I am using the Java 2.0, using Opera Mini, Gmail java app and eBuddy and the new package isnt so much of a upgrade for me... The startup time for Opera has slightly improved but at the cost of gmail loading slower, and my Hyves application fails to load completely (even after reinstalling)
Sorry it took this long to reply but I was finally able to check this.
It seems that Hyves application start-up issue was limited to the first beta release. Application start-up problem was related how bluetooth was opened.
Updated beta package available on betalabs download page seems to have solved this issue.
Please, let us know if you are still having issues with Hyves.
